Indeed, actually it's the compiler that's used in the entire
Opensource software world, plus on some operating systems that don't
ship a compiler by default (like Solaris).  gcc is much older than
Linux, btw.

It also needs a machine-dependant part for the AVR, originally written
by Denis Chertykov.  gcc largely divides the machine-dependant and the
machine-independent parts of the compiler.

For the machine-independent part, yes.

That's the prerequisite for the compiler, this package contains things
like the assembler and the linker.  Again, both are modified version
of the widely used GNU assembler and linker.

That's the compiler for the AVR.

That's the C library, which adds value to the compiler so you can
actually start using it for a specific AVR part you're going to
program to.  It minimally provides you with some runtime support that
links before your own code and takes care of initializing variables
etc.  Additionally, it provides a subset of the C standard library
functions.
